Bloggers, publishers and agency teams can install OptinMonster on any website through a script, or on WordPress through a plugin. It locks gated content behind a form that a visitor fills in to see it. It also attributes revenue to each campaign, showing what every offer brings in. The form fields are limited, with few field types and no file upload, and the templates are not very customizable.
An online retailer can run unlimited Sleeknote campaigns across unlimited domains. Sleeknote hands out a unique discount code from an uploaded list, so each shopper gets a different one. It also shows product recommendations inside a popup on a retail page. Leads sync directly to a defined set of email and SMS tools, which fits teams already on Klaviyo or Mailchimp.
OptinMonster's users praise the quick support and the many ready-made templates that let a campaign go live fast. They also like its strong targeting and testing for lead capture. Some find the interface confusing and say it takes a learning curve, and some call the price high for small businesses. Sleeknote's reviewers like the easy setup and the supportive team. They value smart triggers that personalise popups, though a small business finds the pricing by visitor steep.
OptinMonster describes a marketing agency that helps companies grow through social media advertising. It used the tool to turn site visitors into email subscribers for drip campaigns, and the visitor-to-subscriber conversion rate rose sharply within a month. One Sleeknote customer was a Danish beauty retailer. It wanted more newsletter sign-ups and fewer abandoned carts. The retailer gathered a large number of newsletter leads, and cart abandonment dropped.
